Context
I've built and deployed a javascript app using Heroku that has a Stripe integration for subscription payments. My domain is hosted by GoDaddy but the SSL and app are hosted on Heroku -- only the domain DNS and my domain redirect sit on GoDaddy.
Problem
The stripe webhook works in my test environment but is giving me ERR Timed out connecting to remote host in production and I believe it's because the DNS routing in GoDaddy fire-walling the webhook traffic (Heroku doesn't firewall and the Stripe API call from my app works so the secret keys are properly configured).
Question
How do I add stripe's web or IP addresses to my GoDaddy allow list so the firewall permits inbound traffic from the Stripe webhook?
This was user error on my part. I had incorrectly directed the user to https://mywebsite.com instead of http://www.mywebsite.com in my code.
Once I changed the code the networking issue was resolved.
